What is horsepower (hp) used for?

Horsepower is a traditional unit of power used to rate engine output for vehicles, motors, pumps, and some industrial machinery.

Why use erg per second (erg/s) instead of watts?

Erg/second is the CGS power unit used mainly in astrophysics and theoretical physics where SI units like watts are not preferred.

Does the variant of horsepower affect the conversion?

Yes, different horsepower types like mechanical or metric have slightly different values, so selecting the correct one is important for accuracy.
